To all whom it may concern:

Be it known that I, PHILiP G. HUBERT, a

citizen of the United Statesfresiding at Los Angeles, California, haveinvented a lowing is a specification.

My invention relates to a new and improved construction in waterheaters.

The object of the invention is to provide a simple, non-explosive waterheater having the greatest possible economy in the consumption of fuel.I

Another beneficial feature of my invention is the means provided forpreventing damage if any of the pans-become leaky or overflow. The meansby which these beneficial results are accomplished is illustrated in theaccompanying drawings in which- Figure 1 is a bottom plan view of. acomplete heater. Fig. 2 is a longitudinal section taken on the dottedline y--y in Fig. 1.. Fig. 3 is a transverse section taken on the dottedline m-m in Fig. 1. 'Fig. 4 is a fragmental side view of one of thepans.

Throughout the several views like characters refer to like parts. I

In the details of construction 1 indicates the bottom pan. This .pan isrectangular in shape and is built with a rectangular burner space 5extending longitudinally The inner walls of this pan surround the burneron four sides. A placed directly 1 with its center over and This pan ismade 1 and spaces are left the pan 2 and the in- The spaces thus formedthe passage of the burnfrom the burner 19. The pan 2 is supported bymeans of the apron 7 attached to each end of said pan and fitted andshaped to enter end of the above the pan parallel to the burner.

serve as" fines for pan 1.

'ing an annular double that left top edges engage supported over the pan3 by aprons 9 in the same manner. T he pan 4'is rectangular in shape,has a circular vent formed through its center for the'passage of heatand gases. A vent pipe 10 is connected with the vent in pan 4 and servesto carry away the fumes. A cover 11 is used to inclose'the heater. Thepipe 10 has a jacket 12 with an opening 13 into which the water issupplied from the pipe 14. The jacket 12 is supported by the cover 11 inthe manner shown. 15 reof the same width as pan'3. It

fers to tubes projecting above and below the a bottom of the pan 4..

The height of the projection inside the pan governs the depth of. thewater in the an and when the desired .depth is secured the tubes serveas an overflow to discharge the water into the pan 3 below. Each of thedouble compartments in ,the pan '3 has a similar overflow pipe 16discharging into the pan 2. A discharge pipe 17 is provided for the pan2 similar to the tubes 15 and 16. This tube projects abovethe bottom ofthe pan an amount equal to the desired depth of the water. On the underside itextends through t-he pan 1 and into a pipe 18 connectedwith thepan 1. The top of this pipe 18 is flush with the bottom of the pan 1 andis larger in diameter than the pipe 17 leavspace between the pipes 17and 18.

19 is a suitable gas burner.

20 is the gas mixer.

21 is the gas supply p'ipe.

22 and23 are gas and water cocks operated by a. common lever 24. 25 is aU shaped piece of metal placed over the two adjacent edges ofcompartments of the pan Sdirectly under the vent in the pan 4.

The various parts of the heater may be assembled as followsz The pan 1with the burner 19 secured in the 0 ening 5 is placed on asuitable shelfor brac et, (not shown). The burner is then connected with the supplypipe. This pan should be level. The pans 2, 3 and 4 are placed above thepan 1 and supported in their relative positions by means of the aprons7, 8 and 9. The

member 25 is put in the position shown beof the two inclosing sides 6are inserted in the pan 1 and the grooves shown on the the edges of thepan 4,

forming a complete wall on each side. These parts may be bolted orotherwise fastened together but this is not essential. The

vent pipe 10 is then connected with a vent through the pan over theparts thus far assembled. jacket 12 is connected with the cover and the"water supply pipe connected with the opening 13.

In use a light is applied to the burner 19 and. the water and gas turnedon simultaneously by means of the lever 24. The fire and heat from theburner passes up around the bottom'and edges of the pan 2 across thebottom and through the spaces bet-ween the compartments of the pan 3.The part 25 here serves to distribute the heat over the bottom of thepan 4 instead of allowing it to pass directly out through the vent.After circulating over the bottom of the pan 4 the heat passes throughthe vent in the bottom of the pan' 4 and out through the vent pipe 10.At'the same time water is sprayed from the pipe 14 through the opening13 uponthe .vent 10 through which the heat is escaping. The water thusabsorbs considerable heat before reaching the pan 4. The water thendistributes over the bottom of pan 4 and overflows through the tubes 15to the pan 3; thence through the tubes 16 to the pan 2; thence throughthe tube 17 to the discharge pipe 18. It is thus seen that no water isdischarged into the pan '1. With the proper amount of fire at the burnerthe water is s'ufiiciently heated when it reaches the tube 17.

One of the'very important features of the invention is the functionperformed by the pan 1. This pan serves to gather and discharge allwater accumulating fl om leakage and sweating. The aprons 7 and theinclosing sides 6 convey all Water escaping from the pans above intothis pan. Should 4. The cover 11 is placed The a leak develop while. theheater is not in operation this pan gathers the leakage and preventsdamage to the floors and walls of the building. The-aprons 8 and 9 guideany leakage at the ends of pans to the inside ofthe next pan below andthe several aprons also provide a simple means for leveling up andsupporting the several ans. With this arrangement for caring for eaksthe heater may be used for a long time even after small leaks develop.

Having thus described my invention What I claim as new and desire tosecure by Letters Patent is In a water heater: the combination of a pan1 for collecting leakage and moisture due to sweating; a discharge pipe18 in the bottom of said pan; a gas burner 19 secured within arectangular burner space in said pan 1; a pan 2 supported by aprons 7above said pan 1; a tube 17 for discharging overflow from pan 2 intopipe 18; a double compartment pan 3 supported by aprons 8 above said pan2; suitable overflow pipes 16 in said pan 3: a pan 4 supported by aprons9 above said pan 3; suitable overflow pipes 15 in said Dan 4; a suitablevent passing through said pan 4 adapted to carry off the burned gases;said aprons 7, 8 and 9 adapted to support said pans 2. 3 and 4 and alsoto direct leakage from either of said pans to the pan below; suit-ableremovable sides 6 adapted to inclose the sides of said pans the bottompan 1; a suitable outer cover inclosing-said pans; a jacket pipeconnected with said cover and surrounding said vent pipe; and a suitablewater supply tube for admitting water to said jacket.
